ArrayTyBuilder?

When rewriting bindgen I got shocked this didn't exist.

I implemented a basic version over here, but a more complete solution would be appreciated.

I can try to take time to make a PR soon-ish, but I can't promise anything :)

missing docs for `AstBuilder::struct_`

(and probably outdated somewhere as well)

Update for specialization

ast::TraitImpl has a new field, defaultness.

    pub defaultness: Defaultness

There's a new enum ast::Defaultness.

pub enum Defaultness {
    Default,
    Final,
}

Broken on 1.11.0-nightly (5522e678b 2016-06-20)

Due to the removal of GatedCfgAttr in rust-lang/rust#34272.

For some reason the nightli.es build 11 hours ago ran with rustc 1.11.0-nightly (bb4a79b08 2016-06-15)... possibly related to serde-deprecated/syntex#76 (comment).

I'm assuming clippy is marked as a dependency because it's used by developers. For downstream consumers of the library like quasi_codegen, it causes unnecessary breakage due to unstable APIs.

build is broken

Just a FYI - aster stopped compiling for me today. I'm not sure why exactly because I didn't use multirust to update my rust environment.

I'm unable to work in Rust atm until I find a workaround.
I should probably be using Cargo.lock better...

I just upgraded to the latest rust nightly-2015-10-27 and I still get errors like:

src/item.rs:473:39: 473:43 error: mismatched types:
expected syntax::ast::VariantData,
found syntax::ptr::P<syntax::ast::VariantData>
(expected enum syntax::ast::VariantData,
found struct syntax::ptr::P) [E0308]
src/item.rs:473 let struct_ = ast::ItemStruct(data, self.generics);

etc...

Docs link is dead

https://erickt.github.io/rust-aster/aster (from the project description) is a 404.

The current version of aster depends of syntex_syntax >= 0.6.0 but it obviously shouldn't...
I tried to manually require syntex and syntex_syntax 0.6.0 in my Cargo.toml but it doesn't help. Both quasi and aster continue to pull 0.7.0.

Does not build on nightly >= 2015-12-05

Noticed when Diesel's build started being red. Looks like it's due to rust-lang/rust#29850. Gonna take a swing at this, but opening an issue in case I don't finish this morning (going on vacation, w/ the worlds slowest internet atm)

feature request: simplify cast generation

It would be nice to have functionality in aster to generate things like

let i = 1_u32;//possible
let j = i as u64;//not possible at current version

Not Compiling Against 1.7.0-Nightly

I'm having issues with compiling aster 1.9.1 on the latest rust nightly. It looks like a couple of missing bits. It does work on the 1.6.0-nightly.

I'm not actually depending on aster directly, just through serde.

`ast::LocalSource` has been removed

The enum ast::LocalSource has been removed in the latest nightly, but stmt.rs uses it.

API consistency

Builder interfaces already have many regularities. Here's what can be done to make them more regular.

fn new_with_callback
- Should be renamed to with_callback.
- Sometimes takes additional arguments.
Invoking sometimes implicitly finishes building. E.g. building continues when an expr is built for ConstBuilder, but building ends when a type is built.
fn build sometimes takes additional arguments.
All use of To... traits can be replaced with std::convert::Into.

Builder for modules

There is no way to use Aster to build modules (ItemKind::Mod).
